4 Dead Including Suspect in Shooting, Chase

A shooting suspect and three others are dead after a high-speed chase through two counties ended in a deadly crash and standoff in west Broward Wednesday morning. NBC 6's Myriam Masihy reports. (Published Wednesday, Sep 18, 2013)

Feliu, 48, turned a gun on himself following the tragic sequence of events that began with a double shooting in South Miami Heights and ended with a fatal crash and standoff in west Broward Wednesday.

Police said Vivian Gallego Martinez, 51, and daughter Anabel Benitez, 28, were found shot at their home at 12341 Southwest 190th Street early Wednesday. Martinez died at the scene, and Benitez was pronounced dead at a hospital.

The vehicle Feliu was driving, a dark Mercedes SUV, matched the description of the car police were looking for in connection to the shootings and a chase ensued after he refused to stop, police said.

Feliu drove north into west Broward, speeding and weaving in and out of traffic before his SUV collided with another Mercedes at the intersection of Griffin Road and U.S. 27, authorities said. The violent collision killed the driver of the other car, identified as 48-year-old Maritza Medina, according to the Broward Sheriff's Office.

Officers surrounded and approached the car but heard a gunshot and backed off. More than an hour after the crash, SWAT teams converged on the car and discovered Feliu inside, dead of an apparent self-inflicted gunshot wound, the BSO said.

Police said Feliu once dated Martinez and detectives are exploring the possibility that Feliu may have been angry over a split between them.

Medina's funeral will be held this weekend at the Caballero Rivero Woodlawn at 11655 SW 117th Avenue in Miami. The visitation will on Saturday from 2 p.m. to 12 a.m. and the funeral at 11 a.m. on Sunday.
